PENINGKATAN KETERAMPILAN BERPIKIR KRITIS PESERTA DIDIK MELALUI MODEL PEMBELAJARAN INKUIRI TERSTRUKTUR PADA MATERI TEKANAN ZAT

IMPROVEMENT OF LEARNERS' CRITICAL THINKING SKILLS THROUGH STRUCTURED INQUIRY LEARNING MODELS ON SUBSTANCE PRESSURE MATERIALS 

Penelitian ini bertujuan mendeskripsikan peningkatan keterampilan berpikiri kritis peserta didik melalui model inkuiri terstruktur pada materi tekanan zat. One group pretest-posttest design sebagai rancangan penelitian. Responden penelitian yaitu kelas VIII B berjumlah 22 peserta didik. Teknik pengumpulan data menggunakan metode tes dengan instrumen berupa lembar pretest dan posttest. Hasil penelitian menunjukkan bahwa terdapat peningkatan keterampilan berpikir kritis peserta didik dibuktikan dengan rata-rata nilai N-Gain yang diperoleh pada kriteria tinggi, dimana 18 peserta didik dalam kategori tinggi dan 4 peserta didik dalam kategori sedang. Hasil uji-t menunjukkan nilai signifikansinya sebesar 0,000<0,005 menandakan ada perbedaan keterampilan berpikir kritis peserta didik menjadi lebih baik setelah diterapkan pembelajaran menggunakan model inkuiri terstruktur. Berdasarkan hasil tersebut, dapat disimpulkan bahwa keterampilan berpikir kritis peserta didik dapat ditingkatkan melalui model pembelajaran inkuiri terstruktur.

This study aimed to describe the improvement of students' critical thinking skills through a structured inquiry model on substance pressure material. This study was a pre-experimental design with one group pretest-posttest design as a research design. The respondents of the study namely class VIII B totaled 22 students. The results showed that there was an increase in students' critical thinking skills as evidenced by the average N-Gain score obtained on the high criteria, where 18 students were in the high category and 4 students were in the medium category. The results of the t-test showed a significance value of 0.000<0.005 indicating that there was a difference in students' critical thinking skills for the better after implementing learning using a structured inquiry model. Based on these results, it can be concluded that the critical thinking skills of learners can be improved through the learning of structured inquiry models.
